I have a cast iron dutch oven that I really wanted to like for sailing, but it actually kind of worries me. It is so much dense weight I am afraid it will get loose and punch a whole through the hull in rough weather.

However, I do bring it with me for canal cruising where I know I wont run into any dirty weather, which I do a fair amount of.

It really is the best pot I have used for cooking over an open fire on the beach. The heat is really even and easy to control for cooking on an open fire. I don't cook with it on board, I use a stainless pot for that.
